Anyone getting pretty bad static while on the phone? When no one is talking, it is really quiet with no static at all. Right when the person on the other line starts talking, I hear a lot of static and I have to ask them to repeat themselves. This is while they are on their landline but happens when they use their cell phone too. It doesn't happen with just one person, but everyone. I also tried *228 but that didn't help. Any suggestions?
